Key result
Two-dimensional speckle tracking is feasible for assessing right atrial deformation, establishing a normal global peak atrial longitudinal strain of 49 ± 13%.
Why the study?
What are the reference values of right atrial longitudinal strain indices measured by two-dimensional speckle tracking in healthy individuals?
Observational (n=84)

Provides initial RA strain reference ranges in healthy subjects; leaves open validation and clinical utility.
Padeletti et al. (2011) conducted an observational in Healthy (n=84). Two-dimensional speckle tracking was evaluated on Global peak atrial longitudinal strain (PALS). Two-dimensional speckle tracking is feasible for assessing right atrial deformation, establishing a normal global peak atrial longitudinal strain of 49 ± 13%.
